- CDC confirms 153 cases of Enterovius D68 in 18 states
- California also confirmed four cases of EV-D68
- Canada confirms three cases in British Columbia
- Virus worsens breathing problems for children who have asthma
Enterovirus D68 is likely coming -- if it hasn't already -- to a state near you.
Since mid-August, the Centers for Disease Control and Prevention had confirmed 153 cases of respiratory illness caused by Enterovirus D68 in 18 states: Alabama, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Minnesota, Missouri, Montana, Nebraska, New Jersey, New York, Oklahoma, Pennsylvania and Virginia.
The California Department of Health has confirmed four cases in patients in San Diego and Ventura counties.
And "in the upcoming weeks, more states will have confirmed cases of EV-D68 infection," the CDC said in a statement Wednesday.
"Several states are investigating clusters of people with severe respiratory illness, and specimens are still being tested for EV-D68. It can take a while to test specimens and obtain lab results... These increases will not necessarily reflect changes in real time, or mean that the situation is getting worse."
Canadian health officials have confirmed three cases of Enterovirus D68 in British Columbia. A fourth suspected case from a patient with severe respiratory illness is still under investigation.
Two of the confirmed cases are children between 5 and 9, said Dr. Danuta Skowronski, lead epidemiologist on emerging respiratory viruses at the British Columbia Centre for Disease Control. The third is a teen between 15 and 19.
Enteroviruses are very common. The CDC estimates that 10 million to 15 million infections occur in the United States each year. These viruses usually appear like the common cold; symptoms include sneezing, a runny nose and a cough.
Most people recover without any treatment. But Enterovirus D68 seems to be exacerbating breathing problems in children who have asthma.
The virus is hard to track as many enteroviruses cause similar symptoms and hospitals generally do not test for specific types. But health officials have asked doctors to send in samples if they suspect that Enterovirus D68 has caused a patient's severe respiratory illness.
Enteroviruses "tend to have a summer-fall pattern," Skowronski said, so the high number of cases will likely subside over the next few months.
In the meantime, parents should be on the lookout for the symptoms of Enterovirus D68. Unfortunately, in the beginning it's difficult -- if not impossible -- to tell the difference between a regular cold and this type of virus. But if your child develops a fever or a rash, or if he has difficulty breathing, seek medical attention right away.
Children with asthma or a history of breathing problems are particularly susceptible for severe symptoms.
